20:02 <anderscs> Hi, I have a problem using the vanilla default.nix to build a stack project:

20:02 <anderscs> nix-build --show-trace

20:02 <anderscs> trace: To make project.stack-nix for project a fixed-output derivation but not materialized, set `stack-sha256` to the output of the 'calculateMaterializedSha' script in 'passthru'.

20:02 <anderscs> trace: To materialize project.stack-nix for project entirely, pass a writable path as the `materialized` argument and run the 'updateMaterialized' script in 'passthru'.

20:02 <anderscs> these derivations will be built:

20:02 <anderscs> /nix/store/dqjvcxjq4ypq14j3annpfbc68jjp18i7-project-coverage-report.drv

20:02 <anderscs> building '/nix/store/dqjvcxjq4ypq14j3annpfbc68jjp18i7-project-coverage-report.drv'...

20:02 <anderscs> cp: missing destination file operand after '/nix/store/ks5c31jhxks64mhwncnlr5wzf6bqn7n0-project-coverage-report/share/hpc/vanilla/mix/'

20:02 <anderscs> Try 'cp --help' for more information.

20:02 <anderscs> builder for '/nix/store/dqjvcxjq4ypq14j3annpfbc68jjp18i7-project-coverage-report.drv' failed with exit code 1

20:02 <anderscs> error: build of '/nix/store/dqjvcxjq4ypq14j3annpfbc68jjp18i7-project-coverage-report.drv' failed

20:03 <anderscs> It seems some parameter to cp is missing in project coverage?

20:04 <__monty__> Hmm, someone else ran into a similar issue recently.

20:05 <__monty__> You don't want to build default.nix, you wan to build one or more of your components.

20:05 <__monty__> nix-build -E '(import ./default.nix {}).ProjectName.components.library/exes.ExeName'

20:07 <anderscs> The getting started text could be more clear on that

20:10 <__monty__> anderscs: Which part in particular? I actually don't see any references to nix-build without specifying the attribute. Which is a better way of doing what I just said : )

20:12 <anderscs> The confusing part is that it says building components and I assumed then the default was building everything.

20:13 <__monty__> That is true but there's attributes you don't actually want to build.

20:13 <__monty__> Like that coverage report.

20:19 <anderscs> True, but maybe a sentence to clarify that would make the journey easier for some
